MOTOR-VEHICLE.

SPECIFICATION formingpart of Letters Patent No. 666,085, dated January 1 5, 1901.

Application filed June 2, 1900- Serial No. 18,849. (No model.)

.T all whom t may concern.:

Beit known that I, ROBERT H. CLOUGHLEY, a citizen of the United States, residing at Parsons, in the county of Labette and State of Kansas, have invented certain new and useful Improvements in Motor-Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to motor-vehicles, and more particularly to the driving system and compensating gearing.

One object of the present invention is the provision of ball-bearings for the driving- Wheels, giving such a mounting for said wheels in relation to thedriving system that the friction and heavy strain put upon the axles and compensating gearing commonly existing in motor-vehicles when turning a` A corner or circling around will be entirely ob-` viated, thereby insuring great mobility with a minimum amount of friction and strain on all the operating parts.

Another object is the provision of an improved axle construction which will prevent all sticking and binding not only when the vehicle is moving straight ahead, but also when the compensating mechanism is in use, and which will insure perfect freedom of ac-4 tion in said compensating mechanism, reducing friction and strains therein. To accomplish this object, I construct the axle in different parts in an improved and novel manner and provide improved means for preventing longitudinal play of the parts, thrust antifriction devices, and dust-excluding means.

A further object is to equalize the pull on the compensating gearing and to minimize the size and Weight thereof, as well as to insure continuous action in case of injury or breakage of the power-transmitting means. To accomplish this object and provide a convenient drum for a friction brake-band, I provide a pair of sprockets and position the compensating mechanism between them, employing two chains from the speed mechanism for the Vrespective sprockets. With this construction when the brake is applied the strain is much less in the compensating gear and on the axles than it would be if the comits outer ends.

pensating gearing were located on the side of the sprocket, as in ordinary constructions.

Another object is to house the compensating gearing and to provide a novel arrange ment of balLbearings which Will take up the thrust and insure a perfect and easy action of the bevel-gears and pinions and prevent any crowding and breakage thereof.

An additional object is the provision in the compensating gearing of what I shall term a collar-Wheel, which will perform a number of oftieesin a novel manner, such as spacing the bevel-gears and preventing any crowding action therein, retaining the rollerbearings inv position and also the axles, and holding the pinion-studs in position.

A still further object is to provide in the compensating gearing a novel construction of pinion-stud as combined with the collar- Wheel and the case which will prevent all sticking and afford the greatest ease in the `action of the pinion, a further object being hereinafter and recited in the appended claims. y

In the accompanying drawings, Figure 1 is a longitudinal section of my improved driving and compensating mechanisms; Fig. 2, an enlarged sectional detail of the parts at the center of Fig. 1, and Fig. 3 a similar view of the parts at the ends of said figure.

Portions of the vehicle-frame,which are angular in cross-section, are shown at 1 and 2 to receive the driving-boxes 3 and 4.

The numeral 6 designates a central solid axle, which is provided with ball-cones 7 on There are two hollow axles 8, located in longitudinal alinement and journaled in the driving-boxes. At their outer ends said hollow axles are externallyrecessed at 9 and internally recessed at 10, While they are similarly recessed at 1l and l2 at their inner ends. In the recesses 9 are suitably keyed the flanges 13, which are bolted to flanges 14, secured to the driving Wheels, which have balls 16 interposed between them and the cones 7. The driving-Wheels are there- IOO fore free to turn on ball-bearings on the solid axle and independently of each other, the advantage of which will be apparent hereinafter. In the recesses l0, surrounding the solid axle 6, are the circular series of roller-bearings 18. The seating of the rollers in the recesses or grooves prevents their displacement in one direction, while the driving-Wheels hold the rollers 17 in position, and a collarwheel19, located on the solid axle between the sets of rollers 18, prevents displacement 'of the latter. The roller-bearings reduce friction between the hollow axles and the solid axle to a minimum both when the machine is moving straight ahead and when it is being compensated, reducing friction in the compensating gearing itself and preventing all sticking and binding which would otherwise occur if the bearings were omitted.

To prevent longitudinal play of the axles and exclude dust, I provide the sleeves 20, which are located between the driving-boxes and are secured to the hollow axles `by the set-screws 21, which permit of necessary adjustments. The ends of the sleeve 22 lap over or overhang the drivin g-boxes, and within these telescoping parts of the sleeves are ball thrust-bearings 23, which relieve end friction. The construction described exclu des dust.

The collar-wheel 19 is loose on the axle 6l and is faced perfectly true at both sides and turned perfectly circular on its periphery. On opposite sides of this collar-wheel are bevel-gears 24 and 25, which vare seated in the recesses 11 and keyed to the axles 8 at 26. The inner ends of the axles, the inner ends of the rollers 18, the inner ends of thekeys 26, and the inner faces of the bevel-gears all abut on the smooth sides of the collar-wheel, which retains them in their proper position, so that the rollers cannot become displaced nor the keys work out nor the bevel-gears crowd in and pinch the pinions or break them.

On the hubs of the bevel-gears are the sprockets 27 and 28, between and bolted to `which is a recessed band 29, of annular shape,

to which a band or friction brake can begapplied. The sprockets and the band constitute a case or housing for the compensating Vmechanism, which protects itl and excludes dust The sprockets are provided with ball thrust-bearin gs 30, located in recesses in their inner faces and interposed between them ,and the bevel-gears. These bearings allow the bevel-gearito turn without appreciable friction lwhen compensating. The sprocketsare also provided with inclined oil-cups 30, located in j suitable juxtaposition to the bevel-gears and 6o` which keep the different bearings and operating-spaces properly lubricated.

' In the inner face of the band 29 I provide a suitable number of stud-pockets 32- in the present instance three in number-for the reception of the ends of the pinion-studs 33, which have the heads 34, conforming tothe curve of the band, while the inner ends of eaoss `ions to stick, bind, or work hard, and they are always free for easy action.

By providing two sprocket-wheels disposed v0e' Opeeste Sides 0f the eempensaringgearing the strains are equalized during compensationand when the brake isapplied andV the ifriction is minimized, while continuous action is insured, becauseif one of the sprocketch'ains should break the vehicle could still be ,operated satisfactorily with the remaining chain. At thesame time the parts are all in- ,closed and` protected from dust and injury.
